.The KIA4N65HD is a MOSFET N-channel Trench 650V with 3A 4V @ 250uA 3 Ω @ 1.5A,10V. It is enclosed in a TO-252-2 (DPAK) RoHS package and manufactured by KIA. The MOSFET is used to regulate and control the flow of electric current, making it a great device for high-frequency switching applications, such as power inverters, automobile systems, robotics, and electric vehicles. Due to its low ON-resistance, it offers high switching speeds, low power management, and high efficiency ratings. Additionally, the KIA4N65HD has been tested and certified to meet or exceed industry standards such as RoHS, making it safe and reliable for use in consumer and commercial electronics.
